25 Most Dangerous Chemicals in The World (Health and Safety Awareness)

Chemicals have been parts of our daily life in many aspects. Most of the products we use, we eat, and we consume consist of chemicals. Some of the chemicals are dangerous, but if they are used in a right amount they will be very useful for human’s life. It is known that some industries rely on dangerous chemicals for their production or processing systems, and even though those dangerous chemicals will be attached to the products in the small amount or even none at all, factories need those dangerous chemicals in a big scale.

Transporting and storing the chemicals are not easy, not to mention if the chemicals are dangerous. It has been a challenge for some companies to get permit to use dangerous chemicals, to transport the chemicals and to store it at their warehouse. Not a small amount of money is spent by the companies to provide dangerous chemicals for their production. This procedure needs to be difficult and expensive, so that the dangerous chemicals cannot be obtained easily, because they can be life threatening and a deadly weapon.

Here, we are going to get to know the list of dangerous chemicals in the world, the characteristics and how can they be useful and dangerous.

1. Nitric Acid (HNO3)

Most Dangerous Chemicals in The World is Nitric acid, Some people know nitric acid as aqua fortis or spirit of niter. Nitric acid basically looks like water, with no color or strong smell. However, if we keep it a bit longer, it will slowly change to yellowish. We can easily find nitric acid with concentration of 63% water. The more nitric acid in a composition, the more dangerous and corrosive it is. Non-active metals, like copper and silver, react strongly to nitric acid. However, not all metals react to nitric acid. Gold or other precious metals do not react to nitric acid. It seems like this characteristics make nitric acid useful to identify good and precious metals. Some people use it as the cheap and easy way to recognize gold alloys.

The Characteristics

In a right acid concentration and other variables involved, nitric acid can also be explosive. An interaction between nitric acid and metals in a specific circumstance can cause a very serious damage or even an explosion. Some metals like aluminum, iron and chromium can be easily melted in nitric acid. When reacting to non metals, nitric acid can also be explosive. Hence, nitric acid is commonly used to produce well-known explosives like TNT. Nitric acid turns into yellow nitrated products when it reacts to protein. This may also be resulted from the amino acids contained in the protein.

The Contribution to Industry

Besides being used in producing TNT, nitric acid is also used as the oxidizer for rockets. It can also trace metals in solution, which is very useful for recognizing valuable metals and sort them out from the less valuable ones. Nitric acid can also make wood looks better. And the most familiar thing is, given the corrosive characteristics, nitric acid can make your metal equipments look shiny and clean.

Now, imagine the same reaction take place on your skin. That is how dangerous nitric acid can be. The chemical burns are the common reaction when nitric acid touches our skin. Washing the skin exposed by nitric acid using water is the easiest first aid.

2. Hydrogen Fluoride (HF)
